Abstract

L'invention concerne la métallurgie. Le procédé faisant l'objet de l'invention est du type consistant à traiter la scorie avec un réducteur au carbone dans l'enceinte 1 d'un four électrique, et est caractérisé en ce que le réducteur au carbone est admis sur la surface de la scorie en fusion, en quantité assurant la formation et le maintien d'un lit à la surface de la scorie en fusion, et que des jets d'un gaz ne contenant pas d'oxygène sont soufflés dans ladite scorie à une vitesse et un débit assurant la circulation de la scorie en fusion, y compris sa montée à la surface du lit de réducteur au carbone et son filtrage à travers ledit lit. L'invention s'applique notamment au traitement complexe de scories en fusion des fours électriques en vue d'en extraire des métaux non-ferreux lourds (zinc, plomb, cuivre, nickel, cobalt) et du fer.The invention relates to metallurgy. The method forming the subject of the invention is of the type consisting in treating the slag with a carbon reducing agent in the enclosure 1 of an electric furnace, and is characterized in that the carbon reducing agent is admitted to the surface of molten slag, in an amount ensuring the formation and maintenance of a bed on the surface of the molten slag, and that jets of a gas not containing oxygen are blown into said slag at a speed and a flow rate ensuring the circulation of the molten slag, including its rise to the surface of the bed of carbon reducing agent and its filtering through said bed. The invention applies in particular to the complex treatment of molten slag from electric furnaces with a view to extracting therefrom heavy non-ferrous metals (zinc, lead, copper, nickel, cobalt) and iron.
